WVALTER VANDER I-IEYDEN WILLSON, OF TROY, NEW YORK.

CAR-PLATFO RM.

SPECIFICATION forming part of Letters Patent NO. 422,677, dated March 4,1890.

Application filed October 26, 1889. Serial No. 328,308. (No model.)

To aZZ whom it may concern:

Be it known" that I, WALTER VANDER HEY- DEN WILLsON, a citizen of theUnited States, residing at Troy, in the county of Rensselaer and Stateof New York, have invented cer tain new and useful Improvements in Car-Platforms, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This improvement relates to that class of car-platforms designed moreparticularly for street-cars and especially such as are used withelectric motors; and the invention consists in the peculiarconstruction, combination, and

arrangement of parts hereinafter describec and then definitely claimed.

In the accompanying drawings, Figure 1 represents a plan of my platformwithout the flooring and part of the floor-frame of the car; and Fig. 2is a vertical central longitudinal section of the same with the floor inposition.

Referring now to the details of the drawings, A represents the frame ofthe floor of the car terminating in an end sill A; B B, two longplatform-sills extending from the side sills of the car-frame to thefront cross-sillO, and secured to the main frame by bolts D and clips EE, the latter being shown in dotted lines in Fig 1.

F F are two shorter platform-sills, each of which is fastened to thefront cross-sill of the main frame, and the two diverge until they reachthe front platform-sill, where they are securely fastened by bolts G andform the support for the central part of the platformfioor. Between therear ends of these central sills is a block H, tenoned into them, asshown by the part broken away at X. Below this block is a casting I,forming a box 2' and bearin g for the spring J ,and draw-bar K,whichdraw-bar is pivoted at in the usual manner. This casting is secured tothe under side of the block H by bolts L, which pass through saidcasting I, the sills F, and the front sill of the frame, and by otherbolts M, that pass through the casting I and sills F, and by still otherbolts N, that pass through the casting I and block H.

At the front and rear of the block H are bolts 0, which pass through thesills horizontally, one of which also passes through the block H, andthe other runs in a groove cut in the front of the block, by which meansand the bolts before referred to the short sills, the block H, and thecasting are so thoroughly connected to each other and the front sill ofthe main frame as to be, in effect, one solid piece of great strength.

Platforms for street-cars are usually made with four parallel sills, ofthe same length, running back as far as my sills BBrun. This isobjectionable, inasmuch as the long central sills interfere with thelocation of the rheostats in electric cars of the Thomson-Houston systembut with my arrangement the central part of the frame immediately backof the platform is entirely open, so that there is plenty of room forthe rheostats. Besides this advantage the arrangement of the centralsills, so that they converge toward the frame of the car, forms a veryconvenient connection for the draw-bar K, and thus the materials usuallyrequired to carry the draw-bar box are dispensed with and a muchstronger connection made between the draw-bar and the frame of the car.

WVhat I claim as new isl. A car-platform having two long side sills Band two shorter central sills diverging toward the front of the platformand con nected to the front sills of the platform and main frame,substantially as described.

2. The combination, in a car-platform, of two diverging sills connectedto the front sills of the platform and main frame, and the block H, setbetween and connected with said diverging sills, substantially asdescribed.

3. The combination, in a car-platform, of two diverging sills connectedto the front sills of the platform andmain frame, the block I-I, setbetween said diverging sills, and the casting I, substantially asdescribed.

In testimony whereof I affix my signature, in presence of two witnesses,this 25th day of October, 1889.

WALTER VANDER HEYDEN WILLSON.
